Maneuver Control System (MCS) and the Standard Installation/Division Personnel System (SIDPERS).
(2) Each subordinate system is composed of personnel, procedures, and materiel that
together perform one or more activities of a BFA war-specific or housekeeping function. Housekeeping
functions are similar for all five BFAs and are concerned with providing for intra-BFA communications,
security, and protection of BFA resources, and self-sustainment of these resources.
(3) Information required by a subordinate system to perform its tasks is generated internally
by the subordinate system and externally by the functional control system, other subordinate systems,
and command and control systems of allied nations and other services. These external systems may also
receive information produced by a subordinate system while it performs work-specific or housekeeping
functions. Together, the information inputs required to perform these tasks and the information outputs
produced by them constitute the content of the subordinate system data base. Figure 4-4 summarizes the
essential characteristics of a subordinate system.
